Answer:
B. 60cm
Step-by-step explanation:
The area of parallelogram is calculated by multiplying b × h (b: base, h: height)
the base given here is 5 cm and height is 12 cm
5×12 = 60
Answer:
99
Step-by-step explanation:
A 41 B is a right angle triangle =90 add 41+90 =131 then subtract angle D = 32
so 131-32 = 99 answer I hope it helps u
The surface area would be 9
Answer:
x = 5 , x = 6
Step-by-step explanation:
= x - 5 ( square both sides )
x - 5 = (x - 5)² ← expand using FOIL
x - 5 = x² - 10x + 25 ← subtract x - 5 from both sides
0 = x² - 11x + 30 ← in standard form
0 = (x - 5)(x - 6) ← in factored form
equate each factor to zero and solve for x
x - 5 = 0 ⇒ x = 5
x - 6 = 0 ⇒ x = 6
As a check
substitute these values into the equation and if both sides are equal then these values are the solutions.
x = 5
left side = = = 0
right side = 5 - 5 = 0
then x = 5 is a solution
----------------------------------
x = 6
left side = = = 1
right side = 6 - 5 = 1
then x = 6 is a solution
